Specification of Letters Patent.

The principal object of the present invention is to provide simple meansof a novel nature for securing the flap of an envelop in closedcondition, said means being exceedingly inexpensive being such that theymay be expeditiously applied to an envelop, said fastening meansmoreover being highly effective, and while readily operable, is suchthat there is little danger of the iiap becoming accidentally releasedby handling or during transit in the mails.

In the accompanying drawings, Figure l is a plan view of a rear side ofan envelop showing the flap fastened by the novel means. Fig. 2 is alongitudinal sectional view on the line 2-2 of Fig. l. Fig. 3 is adetail perspective view of a portion of the envelop showing the flapopen. Fig. 4 is a detail sectional -view through a slightly modiiiedform of fastening means.

Similar reference numerals designate coi'- responding parts in all thefigures of the drawings.

Referring to the embodiment disclosed in Figs. l, 2 and 3, the envelopcomprises a body 5, which may be of an f desired shape or character andof any material. The mouth 6 is arranged to be covered by the usual flap7 and the terminal of said flap is preferably reinforced by beingdoubled inwardly, as shown at 8, though with heavier grades of material,doubling is not necessary.

he reinforced portion is provided with a single opening or slot 9.Secured to the rear side of the body of the envelop are oppositelydisposed overlapping inner and outer tongues 10 and il secured at theirouter ends to the rear wall of the envelop body by any suitably means,as for instance, glue. The inner tongue is preferably shorter than theouter tongue, and of less width than the saine, having its free portiontapered toward its rear end and said end being preferably curved or bentinwardly slightly as illustrated in Figs. 2 and 3. The various parts areso arranged that when the flap is turned down to closed position, theinner tongue 10 to manufacture, the parts l may be passed Patented March9, 1909.

It will thus bc evident, particularly by reference to Figs. 1

From the foregoing, it is thought that the construction, o

and it will be understood that various changes in the size, shape,

proportion and minor details of construction,

may be resorted to without departing 4trom the spirit or sacrificing anyof the advantages of the invention.

Having thus fully described my invention,

what I claim as Letters Patent,
